APPARATUS FOR COLORING YARNS.

SPECIFICATION forming part Of letters Patent No. 705,334, dated July 22, 1902.

Application filed February 14, 1902. Serial No; 93,999. (No model.)

' siding at New York, county and State ofNew York, have invented certain new and useful Improvements in Apparatus for Coloring Yarns,of whichthe followingisaspecification.

My invention refers to improvements in apparatus for printing yarns, and more particularly yarns employed. in the manufacture of tapestry and velvet carpets.

The purposes of my invention are to provide simple and efficient means for distributing the coloring-matter properly over and through the yarnafter the same has been applied thereto in streaks and to provide, in connection with printing appliances of usual or other proper construction when equalizing or spreading devices are placed in front as well as in the rear of the distributing-wheel, reliable means for putting and holding such of said devices as temporarily precede the distributing-wheel out of contact with the yarn, to cause such spreading devices where streaks of the same shade of coloring-matter are placed side by side to pass over each of said streaks twice in succession and in oppo site directions, and to also make provision in case an isolated streak of a certain shade of coloring-matter be applied to the yarn to leave the same untouched by any spreading de vices, as is the common custom at present.

In the accompanying drawings, forming part of this specification, and wherein corresponding reference-figures refer to corre-' sponding parts, Figure 1 is a side elevation of an apparatus embodying my improvements, portions of the same being broken away; Fig. 2, a ground plan of the improvements attached to the carriage, and Fig. 8 a ground plan of parts of the apparatus employed in shifting the scrapers or spreaders into and out of their operativepositions, while Fig. 1 is a sectionfalong line 4. 4 in Fig.3 looking toward the left, and Fig. 5 a side ele- Vation of a portion of the appliances illustratedin Fig. 4. Figs. 6 and 7 are detail views of one of the appliances supporting a scraper or spreader, which appliance is attached to the color-carriage, Fig. 6 being a side elevation of one of said appliances with parts broken away, while Fig. 7 ,isan end view thereof. Said Figs. 6 and 7 are drawn to an enlarged scale.

11 is the main body of the color-carriage, and 12 a lid hinged to one end of said carriage. -On each side of the carriage a spring, as 13, is fastened to the main body of the carriage, so as to support said lid and force it upward toward drum let, around which the yarn 15 is wound in usual manner.

16 is the color-box containing the liquid coloring-matter. The same is supported upon iron straps 17, attached to the main body of the color-carriage.

18 is the color-wheel, the shaft 19 of which revolves in proper bearings 20, provided on lid 12, and said wheel is so placed within the color-box and so revolved by proper means that as the carriage is moved along rails 21 21 it will revolve in contact with theyarn and will bring up portions of the contents ofthe color-box and will apply the same in' form of a streakto the yarn wound upon the drum in a continuous uniform layer, and by giving to thedrum successive partial revolutions the entire surface of the yarnon the drum will .becovered with adjoining streaks, a different' color-box with color-wheel being inserted every time a new shade or color is to be applied, in accordance with the design which is to be printed.

The appliances above described and the' mode of employing the same referred to are not part of my invention, as they are now and have been for many years in common use, even before automatic scraping or equalizing of the streaks of color was resorted to in general, and my improvements will be.equally applicable and are intended to be used, as hereinafter described, where modified means for supporting the yarn and for applying streaks of color to the same may be employed.

My improvements refer to the means for equalizing the color which is containedtin the streaks on the yarnand comprise the following features. r a

A bracket'2 l is fastened to each end of the carriage. The vertical arm of each such bracket is hollowed out so as to form a socket, within which a spiral compression-spring 25 is seated. Said spring surrounds a vertical have the scraper which follows after the colorpost 26, which extends through the bottom of said socket and also through a cap 27, screwed to the top of the bracket, and is fixedly secured to said post at 28. As shown more particularly in Figs. 1 and 6, the perforation in the bottom of bracket 24 and that in cap 27 jointly serve to guide post 26 in a vertical direction whenever the scraper is to be moved by the agencies hereinafter described into and out of its operative position. 29 is a T- shaped head adjustablysecured to the upper end of said post by means of a set-screw 30, so as to permit of raising and lowering the head along the post, and the scraper 31 is screwed to such head. The post 26 is so guided on the bracket as to prevent it from revolving around its axis, whereby the alinement of a scraper mounted thereon might be changed. The two scrapers are indicated by 31 and 31 32 is a vertical stud extending downward from the horizontal portion of bracket 24, and

an arm having one end fixedly but adjustably secured to the lower end of post 26, while its other perforated end surrounds stud 32. Said arm carries a horizontal pin 34, serving as fulcrum for a rocking-lever 35, the head 36 of which is adapted to so engage with a suitable bearing-plate on the under side of the horizontal arm of the bracket that when the lower arm of the lever is brought into a position sloping downward toward the colorcarriage spring 25 is permitted to force post 26 upward, so as to hold the scraper under yielding pressure against the yarn on the under side of the drum, while when the lower end of said lever is brought into a position sloping downward and pointing toward the color-carriage and is held there, owing to the contact with said bearing-plate of a spur 37 on said lever, post 26 will thereby be lowered into and held in a position which will cause spring 25 to be further compressed and scraper 31 to assume a position some distance underneath the bottom of the drum and out of contact with the yarn. By raising or lowering head 26 along post 26 the tension under which spring 25 acts may be adjusted as desired. The widths and the alinements of the two scrapers are such as to make each of them capable of covering the streak of color which is in course of application (indicated in Fig. 2 by S and the streak directly adjoining and previously printed and indicated by S. lVhile printing streak S the carriage moves in the direction of the arrow in Fig. 1. \Vhen a series of adjoining streaks of the same shade or color are being printed, it is desirable to wheel travel in contact with the yarn and to hold the other scraper out of contact with the yarn, while when a single streak only is being printed or the first one in a series of streaks it is necessary to keep both scrapers out of contact with the yarn, so as to avoid the rubbing of the color in said streak into an adjoining streak of different color, and I 1 employ the following devices for accomplishing these results.

37 37 are shoes securely fastened to one of the rails 21, from which shoes extend lateral lugs 38, upon which a longitudinal shaft 39 is revolubly mounted, and also depending lugs 40, to which cross-bars 41 are fixedly attached, which cross-bars reach into the space between rails 21.

42 represents lugs secured to bar 39 for the purpose of supporting cross-bars 43, also extending between rails 21.

t4 and 44 are trippers fixedly attached to cross-bars 43, and 45' and 45 trippers so attached to stationary cross-bars 41. Trippers 44 and 45 are placed in line with the lever 35 underneath scraper 31, and trippers 44* and 45 in line with thelever35 underneath scraper 31 ,and said trippers are so positioned with reference to the ends of the drum that as scraper 31 passes underneath the drum and while it is in position sloping downward toward the color-carriage it will strike the under side of the upper end of tripperatet and will thereby be forced into a position sloping downward and away from the color-carriage, whereby scraper 31 will be forced upward against the yarn nearest to the right-hand end of the drum in manner described above. Said lever 35 will remain in such position until it reaches the other end of the drum and scraper 31 has passed beyond the yarn on the drum, when it will strike the upper side of stationary tripper 45 and will pass it. \Vhen the color-carriage travels in the opposite direction, the lever 35 underneath said scraper 31 will strike the under side ofstationary tripper 45 and will thereby be brought into a position sloping downward toward the coloncarriage, whereby said scraper will be brought into its inoperative position. Scraper 31 is then brought into its operative position by having its lever 35 strike the under sideof tripper 44 and will be held there until the direction of the carriage is again reversed. The function of spring 25 is twofold-viz., as set forth above, to force the scrapers against the yarn and also to impart such elastic tension to levers 35 as to permit the same to pass over the trippers in one direction and upon returning to enforce contact between said levers and the under side of said trippers. As the yarn does never entirely cover the ends of the drum an uncovered space of about half an inch or more being generally left there, and as the color-wheel deposits color on said ends it is important to prevent the scraper which follows after the color-wheel from moving such color forward upon the yarn, and this I accomplish in a very simple manner by placing the scraper which is ahead of the colorwheel while the latter is printing a streak in a position lower than and out of contact with the yarn on the drum and by maintaining it at such an elevation until on its return trip it reaches a position underneath the yarn on the drum. By doing so I also prevent striking of said scraper against'the edge of the drum as it passes underneath the latter, thus guarding against injury to the scraping device. In'then raising said scraper and maintaining itin its elevated position until after it has passed entirely from underneath the drum I cause it to push off from. that end of the drum with which it comes in contactlast any surplus color deposited there by the color-wheel.

When a single streak or the first of a series of streaks is to be printed, I place both of the scrapers out of action by means of the following appliances:

46 is a crank fixedly mounted upon shaft 39. The same by means of a link 47 connects with a rod 48, fixedly inserted in a socket 49 integral with a sleeve 50, which is revolubly mounted upon a part 51 of the frame supporting the drum. 52 is another socket also integral with sleeve 50. v

'53 is a treadle which is firmly held in socket 52. When both scrapers are to be placed in their inoperative positions, treadle 53 is depressed, as shown in full lines in Fig. 5 This will cause the movement of link 47 toward the left in Fig. 4 and in consequence will revolve shaft 39 and will swing rod 43 downward in the direction of the arrow in Fig. 4, so as to corresponding with that of the other rod 43,

above referred to. As soon as the carriage has passed completely underneath the drum the treadle may be released. It will thus be seen that while trippers 44 and 45 remain stationary at all times the trippers 44B and 45, being made depressible or movable, may, by actuating treadle 53, be readily thrown into positions which will cause both scrapers to remain out of contact with the yarn while the carriage is traveling underneath the drum.

54 54 are eyes on brackets 29, to which the rope 55 is attached, by means of which the carriage is drawn forward and backward.

It will readily be seen that many of the details, and of the detail combinations herein set forth may be varied materally without departing from the spirit of my invention. Hence I do not wish to confine myself to the use of such details as herein set forth.
